Calibration Instructions

WARNING: Calibrate UPS-III-IS loop calibrators in a safe area.
General
The instrument is supplied by the manufacturer, complete with calibration certificate(s). A
calibration period of 12 months is recommended. The actual calibration interval depends on
instrument usage and the total measurement uncertainty acceptable for the specified application.
The UPS-III-IS is a very precise measuring instrument and the test equipment and conditions of
test must be suitable for the type of work. The calibration check and calibration adjustment should
be carried out in a controlled environment by a calibration technician*.
The manufacturer offers a comprehensive and, if required, UKAS accredited calibration service.
* A calibration technician must have the necessary technical knowledge, documentation,
special test equipment and tools to carry out the calibration work on this equipment.
Calibration Equipment
The following tables give the accuracy requirements for the calibration equipment and the UPS-III-
IS.
Calibration requires a stable temperature of 21° ±1°C (70° ±2°F).
